Outlook 2007: zoom or font change when reading message?

[chrispdixon]

For Outlook 2007: I know how to change the font and size for items in
the inbox, but how can I change the default zoom or size of the text
when reading a message? Usually, the messages appear in HTML format
and the ribbon at the top shows email options like Respond, Actions,
Junk Email, etc. If I reply, it comes up looking like Word and I can
change the default font and size. However, for the reading page, the
only thing I've been able to do is bring up the Zoom dialogue and type
in a zoom percentage each time a message comes up. Is there a way
that I can set a default zoom or text size for the message?

Thanks!
